* unbound: fix local_subnet for IPv6 addresses that contain a portMark Mentovai2022-12-20
| | | | | | | | | | | This prevents a forwarding server named like ::1@5453 from being added to unbound.conf as a forward-host instead of the correct forward-addr. forward-host requires the name to be resolved, which is impossible in the absence of another nameserver. Thus, forwarding-only configurations referencing only the IPv6 loopback address with a port number were broken. Signed-off-by: Mark Mentovai <mark@mentovai.com>

* unbound: clean up interface interpretation in UCIEric Luehrsen2020-11-04
| | | | | | | | | DNS flag day 2020, software should reflect the minimum EDNS 1232 bytes. Added iface_wan and iface_lan to control internal DNS assignemnts and to control what is local service ACL. Interface wild cards are not explicitly set so that they can be customized in extended conf. Signed-off-by: Eric Luehrsen <ericluehrsen@gmail.com>

* unbound: refactor build options to select switchesEric Luehrsen2020-06-27
| | | | | | | | | | The two unique packages "Unbound light" and "Unbound heavy" were not working well due to the fact that Unbound is mostly its library. Tools and helpers would crash. Instead a reasonable default Unbound is built. Also up select options like python are added. libevent and libpthreads are options to down select. Signed-off-by: Eric Luehrsen <ericluehrsen@gmail.com>
* unbound: make option interface_auto default onEric Luehrsen2020-06-13
| | | | | | | | | | Unbound has a quirk and may reply on a different device address. When Unbound answers with from-address different than it received queries on, it may cause trouble for select VPN and firewall configurations. Ensure Unbound replies with the same address by changing this default. Signed-off-by: Eric Luehrsen <ericluehrsen@gmail.com>

* unbound: expose interface-auto to UCIDavid Bauer2020-06-03
| | | | | | | | | | | | | | | This exposes the interface-auto option to UCI. By default, interface-auto is disabled. This leads to the DNS reply possibly originating from a different address then the request was sent to. Devices with a packet filter might not receive the reply in this case. Enabling interface-auto ensures the reply is sent with the source-address the request was sent to. Signed-off-by: David Bauer <mail@david-bauer.net>

* unbound: replace obsolete test expressionsEric Luehrsen2019-05-28
| | | | | | | | Expressions '-o', '-a', and '\( \)' within test or '[ ]' are obsolete. POSIX allows few arguments to test, so long expressions are not portable. '[ p -a q ]' can be replaced with '[ p ] && [ q ]' instead. Signed-off-by: Eric Luehrsen <ericluehrsen@gmail.com>

* unbound: log openssl-1.0.2 lacks TLS host verificationEric Luehrsen2018-08-10
| | | | | | | | | | | ssl_set1_host() is not available without openssl-1.1.0. Unbound can not do host cert verification. DNS over TLS connects, but hosts are unverified. A patch for log err is added with a noitce in README.md. (see: https://www.nlnetlabs.nl/bugs-script/show_bug.cgi?id=658) Also, squash some minor robustness and TLS usability fixes.

* unbound: fix boot time and default run directoryEric Luehrsen2018-08-03
| | | | | | | | | Unbound struggles with boot ifup, so procd triggers changed to push outside of this noise. Unbound has run in /var/lib/unbound/, so chroot (jail) protects /etc/, and it can save flash wear. Compiled defaults reflect this now, so Unbound tools are easier run on the command line.

* unbound: add UCI for forward stub and auth zone clausesEric Luehrsen2018-07-29
| | | | | | | | | | With growing interest, DNS over TLS can be setup in Unbounds foward-zone: clause. A broader UCI solution is added to support forward-, stub-, and auth- zone clauses in a new 'zone' section. This implentation required reworking scripts, because they did not scale. 'forward_domain' and 'prefetch_root' options are removed, and superceded by 'zone' section. Signed-off-by: Eric Luehrsen <ericluehrsen@gmail.com>
* unbound: add README recipe for DNS/TLS outside of UCIEric Luehrsen2018-07-09
| | | | | | | | Unbound UCI so far has limited forward configuration lacking DNS over TLS connection setup tools. User override files 'unbound_srv.conf' and 'unbound_ext.conf' can implement this. Signed-off-by: Eric Luehrsen <ericluehrsen@gmail.com>

* unbound: improve local zone evaluation in UCIEric Luehrsen2018-06-12
| | | | | | | | | | | | When UCI local zone is private and static, Unbound covered private addresses with defaults. Optional delegated global IP6 prefix protection lacked a static zone, but it was prevented from appearing in global DNS responses. Domain names router-as-TLD, "lan." and "local." were static, but they lacked default SOA or NS such as Unbound had assinged to private addresses. Clean up these local zones UCI evaluation and block global DNS inclusion. Signed-off-by: Eric Luehrsen <ericluehrsen@hotmail.com>
* unbound: add root zone file cache optionEric Luehrsen2018-05-28
| | | | | | | | | Add the possibility to use Unbound auto-zone: clause to fetch complete root, arpa, in-addr.arpa, and ip6.arpa zone files. This can speed up recursion when users access many ccTLD or connection logging hits many PTR. Signed-off-by: Eric Luehrsen <ericluehrsen@hotmail.com>
* unbound: provide transparent defaults with documentationEric Luehrsen2018-05-28

* unbound: fix crash when using odhcpd w/o dnsmasqDaniel Gimpelevich2018-01-18
| | | | | | | | | When using the configuration under "Unbound and odhcpd" in the package's README.md, the scripts generated a malformed config file for unbound, due to an "ip route" command giving extra output lines with the string "anycast" where the awk script expects an address. These are now filtered. Signed-off-by: Daniel Gimpelevich <daniel@gimpelevich.san-francisco.ca.us>

* unbound: manage resolv.conf iff when listening on 127.0.0.1#53Paul Oranje2017-06-20
| | | | | | | | | | | | With this patch the unbound init routines manage resolv.conf if and only if when unbound will listen on 127.0.0.1#53 and dnsmasq is not. Also logs some cases where config values are overriden with sane defaults. Fixes (partially) LEDE FS#785 Fixes openwrt/packages#4487 Signed-off-by: Paul Oranje <por@xs4all.nl>
* unbound: add option for dhcp UCI domain mx srv and cnameEric Luehrsen2017-05-23
| | | | | | | | | | | | | | | | Base LEDE/OpenWrt UCI for dnsmasq provides for DNS override in /etc/config/dhcp. It is desired to be able to use dnsmasq and Unbound as transparently as possible. Option 'add_extra_dns' will pull 'domain', 'mxhost', 'srvhost, and 'cname' from base. netifd/procd have an interaction with DHCPv6/RA on WAN (FS#713). Minor IP6 parameter updates can cause Unbound reload events every few minutes. List option 'trigger' selects which interfaces may cause reload. For example 'lan', 'wan' but not 'wan6'. Squash other cosmetics. Signed-off-by: Eric Luehrsen <ericluehrsen@hotmail.com>
* unbound: improve interface trigger behaviorEric Luehrsen2017-03-26
| | | | | | | | | | | | | procd interface triggers may be busy. Unbound hard restarts will flush the cache. This might happen frequently depending on how interface triggers occur. Change the procd trigger to reduce occurences. Load this trigger prior to netifd (START=20), but only truly start Unbound from the trigger rather than immediately in init. Clean up log entries in scripts after Unbound, NTP, and DNSSEC are established. Signed-off-by: Eric Luehrsen <ericluehrsen@hotmail.com>

* unbound: fix hotplug iface and ntp restartsEric Luehrsen2017-03-17
| | | | | | | | | | | | Unbound is configured to restart on hotplug/iface but this can result in numerous restarts at boot. Unbound also has a restart for NTP. This was observed to generate trouble and even with procd robustness too many crashes might occur (rare). Unbound would not be running. Give more care to /var/lib/unbound/root.key during restarts. Use procd for iface restarts. Check pidof() to wait one more second for Unbound. Signed-off-by: Eric Luehrsen <ericluehrsen@hotmail.com>

| | | | | | | | | | | | options 'add_local_fqdn' and 'add_wan_fqdn' can be affected by race conditions when they are at level 4. Interface name may not be returned by network tools. The conf file has bad record formats and Unbound just will not load. Detect this and fall back to only the host FQDN (level 3). squash: improve documentation wording and format codes.

* unbound: improve maintenance of trust anchorEric Luehrsen2017-03-02
| | | | | | | | | | | | | | | | | | | Unbound UCI tries to protect embedded flash from excess use. Unbound RFC5011 KSK tracking can rewrite root.key every few minutes to an hour. It also writes and destroys files in the same directory during the process. Recommended UCI delays for copying busy work in /var/ back to /etc/ may be too conservative. These are all changed from 28 to 9 days. The RFC5011 KSK results were also destroyed by an init.d restart, even if /var/ is mounted on persistent storage like USB drive. /var/lib/unbound/root.key is now preserved during this process, unless a newer key is installed in /etc/ manually or package update.

* unbound: improve robustness with dhcp scriptsEric Luehrsen2017-02-11
| | | | | | | | | | When for example 'package/net/adblock' and DNSSEC vs NTP robustness is enabled, significant restart thrashing can occur at boot up. DHCP lease triggers may be occuring at the same time. Unbounds DNS-DHCP may be incomplete until new DHCP solicit events. Solve this by leaving a passive but complete host conf file during lease trigger. Signed-off-by: Eric Luehrsen <ericluehrsen@hotmail.com>
* Unbound: bug fix odhcpd and add auto adblockEric Luehrsen2017-02-06
| | | | | | | | | | | | | Bug fix dhcp4_slaac6 option was adding to all IP6 routes. Filtering was added to this process to only include addresses served from "this dhcp interface." adblock 2.3.0 file output is now detected and automatically integrated into Unbound local-zones. adblock deposites its block site zone-files into /var/lib/unbound. If this is not desired, then disable adblock or reconfigure to avoid Unbound. Signed-off-by: Eric Luehrsen <ericluehrsen@hotmail.com>
